STRINGSTRING
MBR1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MBR1" - Protein involved in mitochondrial functions and stress response in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

MBR1Protein involved in mitochondrial functions and stress response; overexpression suppresses growth defects of hap2, hap3, and hap4 mutants; Participates in mitochondrial biogenesis and stress response (339 aa)    
Predicted Functional Partners:
ISF1
Serine-rich, hydrophilic protein with similarity to Mbr1p; overexpression suppresses growth defects of hap2, hap3, and hap4 mutants; expression is under glucose control; cotranscribed with NAM7 in a cyp1 mutant; Could influence the NAM7/UPF1 function, possibly at the level of mRNA turnover. Participates in mitochondrial biogenesis (338 aa)
     
   
  0.838
SOK1
Protein whose overexpression suppresses the growth defect of mutants lacking protein kinase A activity; involved in cAMP-mediated signaling; localized to the nucleus; similar to the mouse testis-specific protein PBS13; High copy suppressor of a cyclic AMP-dependent protein kinase mutant (901 aa)
       
 
  0.652
NDE2
Mitochondrial external NADH dehydrogenase, catalyzes the oxidation of cytosolic NADH; Nde1p and Nde2p are involved in providing the cytosolic NADH to the mitochondrial respiratory chain; External NADH dehydrogenase required for optimum cellular growth with a number of nonfermentable carbon sources, including ethanol. With NDE1, performes the mitochondrial oxidation of cytosolic NADH under these growth conditions. Regulates the mitochondrial glycerol-3-phosphate dehydrogenase, GUT2, also involved in cytosolic NADH oxidation (545 aa)
     
 
  0.652
ATG39
Putative protein of unknown function; Acts as a receptor for reticulophagy and nucleophagy. Directs autophagic sequestration of double-membrane vesicles derived from the nuclear envelope and perinuclear endoplasmic reticulum (pnER) into autophagosomes. Is not required for the cytoplasm-to-vacuole targeting pathway, mitophagy, pexophagy, and non-selective autophagy (398 aa)
     
        0.599
HXT5
Hexose transporter with moderate affinity for glucose, induced in the presence of non-fermentable carbon sources, induced by a decrease in growth rate, contains an extended N-terminal domain relative to other HXTs; Probable glucose transporter (592 aa)
     
        0.587
OM14
Integral mitochondrial outer membrane protein; abundance is decreased in cells grown in glucose relative to other carbon sources; appears to contain 3 alpha-helical transmembrane segments; ORF encodes a 97-basepair intron (134 aa)
     
        0.587
AGX1
Alanine-glyoxylate aminotransferase (AGT), catalyzes the synthesis of glycine from glyoxylate, which is one of three pathways for glycine biosynthesis in yeast; has similarity to mammalian and plant alanine-glyoxylate aminotransferases; Has alanine-glyoxylate aminotransferase activity (385 aa)
     
        0.581
YCL021W-A
Putative protein of unknown function (125 aa)
           
  0.578
SAC1
Phosphatidylinositol phosphate (PtdInsP) phosphatase involved in hydrolysis of PtdIns[4]P; transmembrane protein localizes to ER and Golgi; involved in protein trafficking and processing, secretion, and cell wall maintenance; Phosphoinositide phosphatase that hydrolyzes PtdIns(3)P and PtdIns(4)P. Has low activity towards PtdIns(3,5)P2. May be involved in the coordination of the activities of the secretory pathway and the actin cytoskeleton (623 aa)
       
 
  0.544
HAP4
Subunit of the heme-activated, glucose-repressed Hap2p/3p/4p/5p CCAAT-binding complex, a transcriptional activator and global regulator of respiratory gene expression; provides the principal activation function of the complex; Acts a component of the CCAT-binding factor, which is a transcriptional activator and binds to the upstream activation site (UAS2) of the CYC1 gene and other genes involved in mitochondrial electron transport and activates their expression. Recognizes the sequence 5’-CCAAT-3’. HAP4 encodes a regulatory subunit of the DNA-bound complex and seems to provide the pri [...] (554 aa)
